The semen should be deposited either deep in the cervix or at the beginning of the body of the uterus. It promotes uniformity in progeny. Mitosis The cloning of an organism is a form of asexual reproduction. There are three species of elephants. There is no particular breeding season, therefore, they can breed throughout the year. It can readily adopt to almost any climate.

For example, breeding a male Golduck with Nidoran♀ would yield either Nidoran♀ or Nidoran♂.

Livestock Management, Breeding, Systems, Systems of Breeding.

It inherited size and intelligence from the horse and firm footedness, great tolerance and ability to live on rough food from the donkey.

This is how purebreds are produced. Organisms that reproduce through asexual reproduction tend to grow in number exponentially.

A fantastic example of this can be found in Line Breeding for the Pigeon Fancier, Chas.Siegel & Son and also Intensive Line-Breeding by M.H. So, good inbred animals have a better to the exclusion of those of the other parent.

A diploid cell duplicates itself, then undergoes two divisions (tetraploid to diploid to haploid), in the process forming four haploid cells. Most plants have the ability to reproduce asexually and the ant species Mycocepurus smithii is thought to reproduce entirely by asexual means. Duration of heat period varies from 7-9 days. Name the types of nitrogenous bases present in the RNA.

Content Guidelines 2.

(In isogamous species, the two gametes will not be defined as either sperm or ovum.). Line breeding is the process of breeding animals or plants that are closely related so … (ii) Lice— they may be responsible for spread of other infections, irritation.

Generally, after 5 to 6 generations the graded animals will be more or less similar to the pure breed animals that have been used for grading. Out breeding system i.e. European cattle x American buffalo – Catallo Animals with few offspring can devote more resources to the nurturing and protection of each individual offspring, thus reducing the need for many offspring.

i. Inbreeding can be used to form distinct lines or families within a breed.

mating purebred males (sires) to grade or unregistered or crossbred females (dams) to improve the herd. Reproduction is a fundamental feature of all known life; each individual organism exists as the result of reproduction. 4.

Inbreeding 2.

There are about 60 recognised breeds of domestic pigs in the world. For example, if a horse has some qualities that the breeder likes, the breeder could breed that horse with another relative so as to reinforce the desirable traits through a “pooling” of the genes. [21], Sexual reproduction has many drawbacks, since it requires far more energy than asexual reproduction and diverts the organisms from other pursuits, and there is some argument about why so many species use it.

When food sources have been depleted, the climate becomes hostile, or individual survival is jeopardized by some other adverse change in living conditions, these organisms switch to sexual forms of reproduction. Sexual reproduction typically requires the sexual interaction of two specialized organisms, called gametes, which contain half the number of chromosomes of normal cells and are created by meiosis, with typically a male fertilizing a female of the same species to create a fertilized zygote. Why does plant cell possess large sized vacuole?

Some common methods of breeding of cattle, buffaloes, sheep, goats, pigs, horses, donkeys, mules, camels, etc. Sexual reproduction ensures a mixing of the gene pool of the species. This means that the animals do not have any related ancestors in their pedigree for four generations or more. The genetic effects of outbreeding are opposite to those of inbreeding. Depending on the amount of satisfaction, a breeding strength value for the type is calculated, between 0 and 2.

These include haemorrhagic septicaemia, anthrax, foot and mouth disease, sheep pox, black quarter, rinderpest, diarrhoea, fascioliasis and coccidiosis. (ii) Bactrian Camels (Camelus bactrianus): They have two humps, long hair and found in Gobi desert of Central Asia. Image Guidelines 5.

Most breeders of farm animals as well as commercial producers avoid intense inbreeding for the following reasons: i. Undesirable traits appear with increasing frequency as the intensity of inbreeding increases.

The mare produces a single foal at each birth.

[19] Venter plans to patent his experimental cells, stating that "they are pretty clearly human inventions". google_ad_width=120;

What is the reserve food material in red algae? This website includes study notes, research papers, essays, articles and other allied information submitted by visitors like YOU.

In India, it has been claimed that the first buffalo calf in the world bred by means of A.I. The actual programme of line breeding can take a variety of forms, from close line breeding of sire to daughter (or son to dam) to very mild type of line breeding. In human terms, linebreeding is like mating two close, but one-step-removed relatives, like first cousins, grandparent and grandchild, or uncle and niece. Advertisement. Camels breed only during winter months (November to March). Sheep normally mature at about 2 years old. [16] However, viruses are often regarded as not alive. Some species that are capable of reproducing asexually, like hydra, yeast (See Mating of yeasts) and jellyfish, may also reproduce sexually. Linebreeding is a little better, because the parents are one step removed. The two-fold cost of sexual reproduction is that only 50% of organisms reproduce[1] and organisms only pass on 50% of their genes.[2]. v. Inbreeding can be used to study the actual genetic worth of an animal by mating it to 24-35 of its own daughters. The idea is that if one animal has desirable qualities, mating it with a genetically related animal will increase those desirable traits. The yak is highly adapted to cold climates google_ad_type="text_image";

Report a Violation, Animal Breeding: Objectives, Methods and Controlled Breeding Experiments, Process of Plants Breeding : Merits and Demerits of Plant Breeding. Each of two parent organisms contributes half of the offspring's genetic makeup by creating haploid gametes. Content Guidelines 2.

What are the general characters of bryophytes? Foals are weaned when they are 5 to 6 months old.

For example motherxson, fatherxdaughter, brotherxsister, auntxnephew, grandfatherxgranddaughter etc. Line Breeding. But, they have qualities like, adaptability to hot climatic conditions, resistance to many diseases prevalent in the tropical regions (for example Foot and Mouth Disease) and general thriftiness under inferior feeding and management conditions.
